SPECIFICATION forming part of Letters Patent N 0. 731,359, dated June16, 1903. Application filed March 9, 1903. $erialNo.146.922. No model.)

To all whom it ntay concern:

ericksburg, in the county of Spottsylvania and State of Virginia, havemade certain new,

and useful Improvements in Plows, of which the following is aspecification.

My invention is an improvement in plows, andespecially in disk plows andthat class of such plows wherein a wheel-carriage is provided forsupporting the disk-carrying devices; and the invention consists incertain novel constructions and combinations of parts as will behereinafter described and claimed.

In the drawings, Figure l is a top plan view of a plow embodying myinvention. Fig. 2 is a vertical longitudinal section thereof. Fig. 3 isa rear elevation of the plow. Fig. 4 is a top plan view, Fig. 5 a rearelevation, and Fig. 6 a partial top plan view of a somewhat differentconstruction of plow within the broad principles of my invention. Fig. 7is a detail perspective View illustrating the construction employed inthe plow shown in Fig. A for supporting and adjusting the disk-shaft,and Fig. 8 is a detail cross-section on about the line 8 8 of Fig. 7.

Referring now to the construction shown in Figs. 1 and 3, it will benoticed that I employa frame A, supporting the movable parts of thedevice, and to which the tongue B may be connected in any suitablemanner. As shown and as may be preferred, the frame A is fitted upon therear end of the tongue B and may be provided with the side flangeslapping alongside the said beam, as shown in Fig 2. This frame A isprovided at its rear end with bearings A, in which is slidably supportedthe crank-axle C, so the frame can be moved longitudinally along thecrank-axle O in the operation of the device, as will be presentlydescribed. The axle O is provided at its opposite ends with thereversely-projecting cranks O, supporting the wheels 0 and an arm orlever C is secured to the axle, as shown at O and can be operated toturn the axle, and thus adjust the same from the position shown in Fig.3, for instance, to that indicated in dotted lines in the same figure, arack A being provided on the frame A for use in securing the arm orlever O in any desired adjustment.

The shifting-shaft D is journaled in bearings D on the frame A, isBeitknown that I, THOMAS HENRY HARRIS, a citizen of the United States,residing at Fred provided at its front end with a handle or lever Doperating in connection with a rack A on the frame A, by which saidlever may be secured in any desired adjustment, and the shaft D isprovided at its rear end with a crank D to which is connected one end ofa link D whose other end connects at D with the crank-axle C, so theturning of the shaft D may operate to shift the frame A and the partscarried thereby along the axle O in order to adjust the disk presentlydescribed to operate at any desired point. The disk E is supported on anarm F of the disk-shaft F. This shaft F is supported 011 the frame A insuch manner that it may beturned to adjust the disk E from the positionshown in Fig. 1 to that indicated in dotted lines in the samefigure, orvice versa, and may be raised or lowered to set the disk into or out ofposition to cut a furrow in the ground. In the construction shown and aspreferred the shaft F is journaled at its front end in a bearing G, soformed as to permit the said shaft to turn, and also to permit the shaftto be raised and lowered at its rear end, as will be understood fromFigs. 1 and 2 of the drawings. At or near its rear end the main frame isprovided with an upright guide-stand H, within which operates thedisk-shaft F, so said shaft can be raised and lowered, as will beunderstood from Fig. 2. To this stand H, near its upper end, isjournaled a shaft I, havinga crank I,

connected by means of a pitman or link I with the shaft F, so that shaftI maybe turned by its handle I to raise and lower the shaft F at therear end of the latter. The handle I of the shaft 1 may be held in anydesired adjustment by the rack A, mounted on the stand H, as shown inFigs. 1, 2, and 3, so the shaft F may be secured in position to hold thedisk out of the ground or in the ground to any desired extent. A handlelever or arm J is secured to the shaft F, preferably in advance of thestand H, and may be operated to turn said shaft in order to adjust thedisk E to its different positions, catches J being provided on the mainframe in position to secure the lever J in either of its adjustments, aswill be understood from Fig. 1 of the drawings. The shaft F has itsdisk-carrying arm F projecting from its rear end forwardly and ICO at anincline, so it will support the disk E at the desired inclination to theline of draft, so the disk when set from side to side may be adjusted tooperate either as a right or left plow. In the operation of thedescribed construction it will be noticed I provide means whereby theoperator can when sitting in the seat K adjust the crank-axle O byturning the same to raise and lower either side of the machine, canraise and lower the disk, can turn the disk-supporting shaft so as toset the disk right or left, and can shift the main frame along thecrank-axle to secure the desired relation between the disk and thewheels in order to form the furrow in the proper place. I thus providean implement by which the land-furrow may be turned in either direction,by which the depth of the furrow may be regulated as well as the widthof such furrow and in which the disk can be lifted for passing overstones and other obstructionsandin moving from one place to another, andin the use of which the driver can adjust his plow from thedrivers seatand can begin work as soon as the team is in position in the field.Manifestly the axle may be long enough to properly support two or moredisks, as may be desired.

In the construction shown in Figs. 4 m8, inclusive, I present a somewhatdifierentconstruction, whereby to secure the results before described.In this construction I employ a crank-axle similar to that shown inFigs. 1 to 3, such crank-axle 1 supporting the wheels 2 and havingconnected therewith a lever 3, by which the crank axle may be turned,such lever 3 being jointed at 4 to a cuff 5 on the axle 1, so the levermay be turned to the position shown in Fig. '5 to clamp the axle when itis desired to turn the axle 1. This lever 3 also has at 6 a notch toreceive a ing 7, projecting from a lever 8, which connects with thedisk-shaft 9 and which operates to shift the disk-shaft and the mainframe carrying the same along the axle 1. In this construction the mainframe ineludes an upper plate 9 and a lower plate 10 in the form ofcastings and embracing the tongue 11, the lower casting 10 having abearing at 12 for the axle 1 and the castings 9 and 10 having uprightguides 13 for the uprights 14, carrying the drivers seat 15, suchuprights extending at their lower ends below the casting 10 and beingprovided at 16 with a bearing for the disk-shaft 17, which diskshaft maybe raised and lowered at its rear end by means of the crank 18 on theshaft 19, the latter having a handle 20 at its front end and having itscrank 18 engaging in a suitable one of a series of holes 21 in a plate22, which is provided at 23 with an opening receiving the disk-shaft1.7, so the latter can be raised and lowered at its rear end.

Manifestly in the construction shown in Figs. I to 8, inclusive, thedisk-shaft may be reversed from side to side by means of the lever S,the axle 1 may be turned by the lever 3, and the frame be adjusted alongthe crank-axle in a manner somewhat similar to that shown in Figs. 1 to3 and before described. It will also be understood that the constructionshown in Figs. 4 to 8, inclusive, may be employed without departing fromsome of the broad principles of my invention.

Havingthus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
